Abstract
Amplified spontaneous emission power and contrast ratio in a linear miltipass Ti:sapphire regenerative amplifier with a wavelength centered at 1054 nm are calculated and measured. It is shown that the passive losses of a seed pulse and the losses in coupling to the regenerative amplifier cavity mode degrade the intensity contrast ratio to 10(-6)-10(-7). The advantage of an optical parametric chirped pulse amplifier with respect to the contrast ratio is discussed.Year: 2003 PMID： 14717303 DOI： 10.1364/ao.42.007231
